太多的题目,没有提问者自己的见解,懒得回答.
看了楼上最后一句,去看了最后一题,觉得选项有误,不知道你们老师给的答案是什么?
我发现网上以讹传讹的很多：
1.高中一年级英语《期末复习习题精选》 习题精选其它试题
2005年2月18日 ...Sometimes my job is tiring,but ____ I quite enjoy it.
A.at random B.try and large C.in other work D.within easy reach.
这是你的版本,BC选项本身都有问题,很可能是打错了.
2华南理工大学网络教育学院高中起点入学考试英语考试复
2010年5月20日 ...Sometimes my job is tiring,but ______ I quite enjoy it.
A.at random B.by and large C.in other work D.within easy reach
将B改过来了!但C选项还有点莫名其妙,前面说job,后面说work干什么呢?要说也说别的工作,也用job好了,是不是in other words 换句话说?
3.单项填空_写作业吧_贴吧
Sometimes my job is tiring,but ____ I quite enjoy it.
A.at random B.by and large.C.in other words D.within easy reach.
果然,有我想象中的选项!
不过因为“正确”答案不是它,将错就错,无所谓.
最佳选项是B
by and large adv.sometimes considered nonstandard on the whole; in general:
By and large,your idea is a good one.
我怀疑你用的就是第一个出处的题目,要是没有答案,我全给你:
Ⅰ 1-5 ADAAB 6-10 BBDBD 11-15 BCCCB
又发现第三题选项又误抄了,怎么这些人总把by误打成try呢?且答案和题目本身都有误：
3.the population of this city ,forty percent of which ____,____ 15％ in the last three years.
A.are Germans; has risen B.are German; has fallen try
C.is Germans; have increased to D.is Germans; has been reduced try
我看是从下面的网页复制过来的,因为句首也没大写.此题无解.A选项 risen后少了by .B选项第一空are German,没错,可将German看成形容词.但即使将try改为by,此题本身也有问题,问题是,Population这一词,在同一个句子中,一会代表‘people’,为复数概念(非限制性定语人句中which所指代的population),一会代表‘number’（主句中的population),这和汉语中“我打伞和饭”是一样的问题.
